We can't all rely on NTL to play nursemaid to our emails, or what we do on the net. We have to take on some of that responsibility ourselves and it's up to us to make sure we do as much as we can to minimise spam.
I get at least 15 items of spam on my yahoo account...... nothing (yeah, this is odd!) in my hotmail account (it's rare if it does get through!)
I have one email for signing up to things - any resulting spam goes to one inbox.. one email for family/friends (and nothing else) and an email address thats strictly business stuff!
So far, no probs with that
